20 Fenchurch St – In Building Distributed Antenna System (DAS)

The Virtua team were awarded the opportunity to support the owners of 20 Fenchurch Street in London to implement a dedicated in-building cellular solution for the whole building, with the requisite of providing 2G (GSM), 3G (UMTS), and 4G (LTE) services from day one of the building opening.

Multi-Operator In-Building Solution

37 Floors, 160m High, 20,000 people

254 Antennas

Our design engineers surveyed the building during its construction phase. This aided the team with the production of the distributed antenna system (DAS) design. 3D models of the building and each floor were then constructed electronically to aid in the detailing of the proposed coverage.

In parallel to the main system implementation, Virtua conducted numerous trials to provide dedicated coverage to 12 lifts located within the building. Given the speed at which these lifts travel, the restrictions governing the installation of equipment inside the shaft, and then adding to this the construction of the lift itself, this was a difficult technical challenge.

By installing a dedicated in-building system 20 Fenchurch Street now benefits from continuous, seamless, and robust cellular coverage which is critical for workers to be efficient and effective.
